AKM Invites You to View Our New Emerging Technology at CES 2015

At CES 2015, AKM will be demonstrating a variety of innovative technology solutions which can propel consumer electronic devices to the forefront of their market. AKM staff will be available to engage with you in detailed technical discussions about the new technology solutions, as well as business and long term roadmap discussions. AKM will be hosting meetings by appointment in the Las Vegas Hotel.

Energy Harvesting Solutions

Come and learn about AKM’s energy harvesting solutions. AKM has developed voltage detectors and step-up DC-DC converters with industry leading current consumption (20nA) ideal for energy harvesting solutions. Our DC-DC converter can operate from an input power of only 50uW generated from a single solar cell under indoor lighting. This DC-DC converter is not limited to a solar cell input but could be used to generate a usable voltage extremely efficiently from any minute power source.

High Performance Asynchronous USB Sound Card

AKM has developed a bus powered asynchronous stereo input and output USB reference design. This design uses AKM’s brand new high performance CODEC, the AK4558, which achieves 108dB dynamic range for both its ADC and DAC. This system also incorporates a Microchip PIC32 to handle the asynchronous USB to I2S data transfer.

Wireless Dimmer

The demonstration kit consists of a transmitter and receiver to develop a wireless remote switch and dimmer system. On the transmitter, user input is captured using AKMs unique rotational hall effect sensor and is transmitted using the 400MHz ISM band enabled by the AK3711. On the receiver, the AK3701 receives 400MHz ISM band signal and down-converts the signal for a microprocessor to control AP2152N LED driver.
